Also on Tuesday: Martyring Ruby Ridge

Never has there been so many films about white supremacists on public television as there are this Black History Month.

Following a documentary Monday about a man who sits down with KKK members to find their humanity, here’s a followup of Barak Goodman’s film last week about the rise of the white extremists that led to “Oklahoma City” and as such, it includes many of the same interviewees.

The hour-long documentary “Ruby Ridge” on “American Experience” (PBS, 9 p.m., check local listings) makes a martyr out of the guy who put his family in danger by refusing to show up for trial to answer charges of sawing off shotguns. Randy Weaver eventually surrendered 11 days after shots were fired but not until after three were dead including a U.S. Marshall. A surviving daughter who is interviewed (with dramatic music behind her) talks about feeling like she was being hunted. As in Waco, authorities who were patient for a time eventually stumbled into violence. Still, there was a much easier way for this to have ended.
